A webcam that "just works" seems like a herculean task if the goal is to have native compatibility with most devices without installing a package - Chromebooks, Apple, *nix, etc. but given how decent cameras are standard on mid-tier phones, you're spot on

Most webcam's I've tried do "just work" with *nix since they use USB UVC. And most linux distributions come with or can easily install the qt v4l2 package which can show you a live feed and let you adjust all the webcam's parameters that are exposed over UVC - for my current Logitech that's the common stuff like resolution, FPS, brightness/contrast/saturation, but also hardware-specific things like exposure (or autoexposure), pan/tilt/zoom, and focus / autofocus.

I'm pretty sure the situation is the same on ChromeOS and Macs. And I've seen that webcams these days also tend to be pretty plug-and-play on Windows.
